$ZnAl_{1-x};Cr_xO_4$ solid solutions were synthesized as pink pigments with and without mineralizer. The pigments were examined to optimize color development conditions of temperature and $Cr_2O_3$ contents. The characteristics of synthesized pigments were analyzed by XRD, XPS, FT-IR and UV-vis spectrophotometer. While samples without mineralizer fired at $1300^{circ}C$, showed $ZnAl_2O_4$ and $ZnCr_2O_4$ spinel in XRD analysis. While samples with mineralizer resulted in $ZnAl_2O_4$. As a results, the pigments show pink color and most effective pink color was obtained at X=0.15 and $1250^{circ}C$ when mineralizer was used. The chromatic coordinates are $L^*$ 58.61 $a^*$ 24.48, and $b^*$ 9.60.
